翻译:
基于 BBD(桶链式电路)的模拟回声效果器,采样自真实硬件设备。
大多数复古延迟插件的设计始于一份“功能愿望清单”,而这款插件的起点却是一把螺丝刀。我们对一台真实的 BBD(桶链式电路)硬件延迟设备进行了详尽测量——该设备所采用的芯片系列和电路拓扑,正是定义了 80 年代初以来模拟回声特质的核心:包含输入压缩扩展(compander)、与 BBD 时钟频率挂钩的带宽、软削波反馈路径,以及通过饱和产生的自激振荡。我们采集了狄拉克脉冲(Dirac impulses)、对数扫频信号、持续正弦波,以及在十几种不同反馈电平下的饱和曲线。

这款插件完全基于上述测量数据构建,而非源于市场营销需求。例如,决定 300 毫秒重复音色“暗度”的系数(在最低重复率下截止频率为 820 Hz,在最高重复率下为 1037 Hz),直接源自扫频反卷积分析;自激振荡时 11.5% 的总谐波失真(THD),则源自实际振荡回路在 1 kHz 下的频谱特征。整个开发过程中,没有任何参数是仅仅为了“听起来复古”而凭主观听感随意调节的。

在忠实还原硬件模型的基础上,我们还加入了一些原始硬件无法实现的功能,其中最主要的是“三频段频率倾斜(Frequency Tilt)”——它能让低频和高频产生不同的延迟时间。据我们所知,这是其他延迟插件所不具备的特性。向右旋转旋钮,高频会滞后出现,而低频则会迅速响应;向左旋转,低频尾音会变得极长,而高频则保持紧凑且短促。

独特之处:
· 各频段独立的频率倾斜时间控制:独一无二的设计。
· 非对称饱和特性:精确匹配了硬件实测的偶次/奇次谐波比例。
· 多重 LFO 漂移:模拟了磁带机主轴(capstan)、皮带轮(pulley)及轴承摩擦带来的复杂波动,而非简单的单一正弦波调制。
· 内置压缩扩展(Compander)动态响应:直接集成于延迟链路中,而非通过独立的 VCA(压控放大器)模拟。
· 各频段交叉反馈(Cross-feedback)乒乓效果:在启用频率倾斜功能时,可同时呈现三种不同的节奏律动。
· 侧链闪避(Sidechain Ducking)功能:具备内部回退机制,即使未连接侧链总线,也能正常工作。

应用场景
·人声:利用侧链闪避(sidechain ducking)功能,确保回声不会掩盖辅音;向右调节“频率倾斜”(tilt),可营造出仅针对辅音的“空气感”尾音。
·鼓组总线(Drum bus):向左调节“频率倾斜”,可保留底鼓(kick)的回声,同时让踩镲(hi-hat)的瞬态冲击感迅速回归;多频段处理确保了低频的清晰度。
·合成器与铺底音色(Synths and pads):三频段“乒乓”(ping-pong)效果可带来天然的立体声宽度,这是单频段延迟插件无法实现的。
·氛围与质感音效:通过“冻结”(freeze)功能定格声音瞬间,进行多层叠加,并在进入下一乐段时一键清除。

标准控制参数:时间(time)、反馈(feedback)、干湿比(mix)、漂移(drift)、漂移速率(drift rate)、音色(tone,2.5 kHz 处 ±12 dB 高频搁架均衡)、闪避量(duck amount)、频率倾斜(frequency tilt)、干声切除(kill-dry)、冻结(freeze)、清除(clear)以及节拍同步(tap)。支持通道同步(link)、A/B 快照对比与复制功能;内置 6 个出厂预设,并可通过 .xml 格式保存/加载无限数量的用户预设。

功能特性:
·多频段频率倾斜(Multiband Frequency Tilt)
包含三个频段,每个频段拥有独立的延迟时间。通过一个旋钮即可在时间轴上拉开低频与高频的距离——例如低频延迟短、高频延迟长,反之亦然。这是目前市面上其他延迟插件所不具备的独特功能。

·基于采样的 BBD(模拟桶链式延迟)硬件模拟
通过对真实的 BBD 硬件设备进行脉冲响应(IR)测量、扫频测试及饱和曲线分析而构建。所有参数系数均源自真实硬件,而非凭空估算。

·非对称饱和(Asymmetric Saturation)
反馈路径中包含偶次与奇次谐波,精准还原了我们在硬件自激振荡状态下测得的总谐波失真(THD)曲线(在最大强度下约为 11.5%)。

·多重 LFO 漂移(Multi-LFO Drift)
结合了慢速主轴(capstan)LFO、快速传动轮(pulley)LFO 以及经过滤波的随机游走(random walk)调制。真实的“颤音与抖动”(wow & flutter)并非单一的正弦波,我们的模拟亦是如此。

·压缩扩展(Companding,NE570 风格)
在延迟线路前进行 2:1 压缩,在延迟线路后进行 1:2 扩展。重现了经典 BBD 硬件所特有的“呼吸感”或“抽吸感”(pumping effect)。

·跨频段“乒乓”效果(Cross-Band Ping-Pong)
每个频段均可独立进行“乒乓”式左右声道交替延迟。通过调节“频率倾斜”,低频与高频的左右跳跃节奏将不再同步,从而产生更丰富的空间动态。轻松实现多节奏立体声效果。

·侧链闪避 (Sidechain Ducking)
支持外部侧链或内部侧链(以主信号作为触发源)。可自动降低湿信号音量(例如在人声出现时),无需额外加载闪避插件。

·冻结与清除 (Freeze & Clear)
“冻结”(Freeze) 功能可将当前回声锁定为无限循环;“清除”(Clear) 功能则能瞬间停止所有重复音,且不会影响干信号。

·手动定速与同步 (Tap Tempo & Sync)
支持手动敲击设定速度,或与宿主软件同步。各通道均可独立设置同步参数(如 1/4 音符、附点 1/8 音符、三连音 1/16 音符等),并支持通道间联动。

·A/B 对比与快照 (Snapshots)
提供两组参数快照,支持即时切换及相互复制。符合专业插件的标准工作流程。

原文:
BBD-modeled analog echo, sampled from real hardware.
Most vintage-delay plugins start from a wishlist of features. This one started with a screwdriver. We measured a real bucket-brigade (BBD) hardware delay, the same chip family and circuit topology that defined analog echo from the early 80s onward: companded input, BBD clock-tied bandwidth, soft-clipped feedback path, self-oscillation through saturation. Dirac impulses, log sweeps, sustained sines, saturation curves at a dozen feedback levels.

The plugin is built from those measurements, not from a marketing brief. The coefficient that decides how dark a 300 ms repeat sounds (820 Hz cutoff at minimum repeat rate, 1037 Hz at maximum) came straight from the sweep deconvolution. The 11.5 % THD at self-oscillation came from a 1 kHz spectrum of the actual oscillating loop. None of it was tuned by ear until it “sounded vintage”.

On top of the faithful model we added a few things the original could never do, chiefly a three-band frequency tilt that delays bass and treble at different times. As far as we can tell, no other delay plugin does this. Roll the knob right and your highs float behind, basses come back fast. Roll it left and the bass tail is the longest thing in the mix while the highs are tight and short.

What makes it different
·Frequency-tilt time per band: unique, nothing else like it.
·Asymmetric saturation that matches the measured even/odd harmonic ratio of the hardware.
·Multi-LFO drift instead of a single sine: capstan + pulley + bearing-friction noise.
·Compander-pumping built into the delay line, not faked with a separate VCA.
·Cross-feedback ping-pong per band: three rhythms running at once when tilt is active.
·Sidechain ducking with internal fallback so it works even without a side-chain bus routed.

Where it shines
·Vocals: sidechain duck keeps the echo out of the way of consonants. Tilt right for an “air” trail of consonants only.
·Drum bus: tilt left to hold the kick echo and let the hi-hat slap come back fast. Multiband keeps the low end clean.
·Synths and pads: three-band ping-pong gives a built-in stereo width that no single-band delay can produce.
·Ambient and texture: freeze a moment, layer on top, clear when the next section comes in.

Standard controls: time, feedback, mix, drift, drift rate, tone (±12 dB high-shelf at 2.5 kHz), duck amount, frequency tilt, kill-dry, freeze, clear and tap. Sync per channel with link, A/B snapshots with copy, six factory presets and unlimited user presets via .xml save/load.

Features:
·Multiband Frequency Tilt
Three frequency bands with separate delay times. One knob shifts bass and treble apart in time, short bass / long highs, or vice versa. Not in any other delay plugin we know of.

·Sampled BBD Hardware
Built from impulse responses, sweeps and saturation curves measured on a real bucket-brigade unit. Every coefficient comes from the box, not a guess.

·Asymmetric Saturation
Even and odd harmonics in the feedback path, matching the THD curve we measured at self-oscillation (~11.5 % at MAX intensity).

·Multi-LFO Drift
Slow capstan LFO + fast pulley LFO + filtered random walk. Real wow & flutter is not a single sine, and neither is ours.

·Companding (NE570-style)
2:1 compress before the delay line, 1:2 expand after. Gives you the typical “atmen” / pumping feel of vintage BBD hardware.

·Cross-Band Ping-Pong
Each band ping-pongs independently. Tilt the time and the bass and treble bounces are no longer in sync. Polyrhythmic stereo without effort.

·Sidechain Ducking
External sidechain or internal (uses the main signal as trigger). Drop the wet signal under vocals automatically, no extra ducker plugin.

·Freeze & Clear
Freeze locks the current echo into an infinite loop. Clear stops all repeats instantly without bypassing the dry signal.

·Tap Tempo & Sync
Tap a tempo or sync to the host. Per-channel sync (1/4, 1/8 dotted, 1/16 triplet, etc.) with optional link.

·A/B Compare + Snapshots
Two parameter snapshots, instant switch, COPY between them. Standard pro-plugin workflow.
